So if your house has double-hung sash windows, consider they have the following characteristics:

  • A rotating cam right on the frame top of the outside part of the window. It also has a hook linked to the bottom of the frame right at the inner window which helps to make it slide
  • Barrel locks sometimes replace the sash lock, or both can feature in this type of window
  • The top window frame consists of a pivot lock with a pin that fits into some holes right at that spot. Another feature there is a handle shaped like a pancake where you hold to open the window

Horizontal Sliders Lock

Aluminum or vinyl windows have a sliding half side with a hinged catch that is locked onto the frame of the window. In some, the other side of the window may also have a sliding catch that locks to a depressed bottom track. Knowing how to open the horizontal sliding windows means releasing the two locks of the window.

Furthermore, the inbuilt springs help the window to lock automatically. If you don’t know this, you may release only one catch and wonder why the window is not opening.

The pivot locks of the horizontal sliding windows can get stuck sometimes because of one of the two windows moved out of track. To Fix this, lift the window and turn the pivot with one hand to unlock it.

How to Cut Window Glass?

To cut the window glass, you will first of all need access to the tools required since not everyone has them. The best tool to use is a circle glass cutter. As you could guess from the name of the tool, with its help, you will cut a circular hole in your window.

It’s great for a single-glazed pane. If you have a double-glazed window, you will need access to the inside to use this cutter to cut the inner pane. Or, for the inner pane, you could make use of the handheld glass cutter that comes with the circular cutter tool mentioned above.

How to Break Window Glass?

If cutting the glass isn’t an option for you, then breaking the whole pane is the only possible solution.

Breaking the whole pane of glass will allow you to climb through the window, assuming the casement or sash is locked. At this point, be sure to protect your hands, face, and body from the risk of flying glass. Also, be very careful not to cut yourself on any remaining glass shards as you climb through!

Now you know everything one might need to be aware of in terms of opening aa window from outside. With the help of our guide, you will be able to open your window no matter what type of lock it has or why it got stuck.
